Class AttrCompare

java.lang.Object

org.apache.axiom.c14n.helpers.AttrCompare

All Implemented Interfaces:

java.io.Serializable, java.util.Comparator

public class AttrCompare
extends java.lang.Object
implements java.util.Comparator, java.io.Serializable

Compares two attributes based on the C14n specification.

• Namespace nodes have a lesser document order position than attribute nodes.
• An element's namespace nodes are sorted lexicographically by local name (the default namespace node, if one exists, has no local name and is therefore lexicographically least).
• An element's attribute nodes are sorted lexicographically with namespace URI as the primary key and local name as the secondary key (an empty namespace URI is lexicographically least).

Method Detail

compare

public int compare(java.lang.Object obj0,
                   java.lang.Object obj1)

Compares two attributes based on the C14n specification.

• Namespace nodes have a lesser document order position than attribute nodes.
• An element's namespace nodes are sorted lexicographically by local name (the default namespace node, if one exists, has no local name and is therefore lexicographically least).
• An element's attribute nodes are sorted lexicographically with namespace URI as the primary key and local name as the secondary key (an empty namespace URI is lexicographically least).

Specified by:

compare in interface java.util.Comparator

Parameters:

obj0 - casted org.apache.axiom.c14n.omwrapper.interfaces.Attr

obj1 - casted org.apache.axiom.c14n.omwrapper.interfaces.Attr

Returns:

returns a negative integer, zero, or a positive integer as obj0 is less than, equal to, or greater than obj1
